To all whom it may concern:

Be it known that l, lFnn lb. BA, e citizen of the limited Stutes, end u resident of Chico, in the county of Cool; end Stete of lll'inois, hove inven certnin new end useful Improvements in Lubrimting Systems'for Motor Vehicles, of which the following is e full, cleer, end erect deecription.

The invention reletes to lubrioet systones for motor vehicles and its object is to provide on improved system by which the several M orings many he conveniently end periodically lubriceted under pressure. Another object of the invention is to provide on improved system of this t l in which proion is e for lubriceting the beerings hy grevity'it desired.

The invtion cone in the mverel novel ieeturee hereinur set forth end more perticulerly deed by old et the conclusion hereof.

In the drnwings; Fig. l is e diegreetic view oi en eutomohile provided with the invention. Fig. 2 iso view partly in section end portly in elevetion ot the lubricet system.

The invention is enplified in n structure comprising e reservoir 5 which is cl end edepted to retein e considerehle supply ct lubriceting oil. An inlet pipe 6 is connected to the top of the reservoir and is provided with e velve 7 which, when open, will permit oil from u tunnel 8 to grevitete into the reservoir. A stem 9 conteining e chech-velve, such no is usuelly on the irmer tube of e pneumatic tire, is also connected to the top of the reservoir 5 end forms it connection which is adopted to be coee'ted to e. supply of compres eir by which the oil in t e reservoir niey be put under es much pressure es desired. The usuel check-velve in the stem 9 automoticelly closes to retain the pressure in the reservoir us well understood in the ert. The reservoir is usually pieced eteoine convenient point under the engine-hood.

"A pipe 10 is connecto. the hottom of the reservoir 5 end ls into the top of e distributing tenh ll. A valve 12. is in cluded in pipe 10 to control the dew oi oil from the reservoir into the distributing tenh. The stem 13 of this velve is eded reerwerdly through the dushboerd' 14 end is provid with e h 15 within convenient reach of the driver of the eutomobile. A series of pi 16, usually formed ct co per ere connected tothe bottom of the distributer tank by couplin 17 and l to the difi'erent bearings which ore to he periodicelly lubriceted. Pipes 16 ere usuelly connected to flexible pipe motions 16" perticnlerly where the beerings move relatively to the chessis on. which the tenh end voir are supported. The upper portion of the distributer tank 11 slopes from the ends to the pipe 10 so esto prevent eir hots from being formed es the ult of the movement of the vehicle when there is u colof oil in the tenk.

A. vent pi e 18 is. cone to the top off the distri uter to end extends reorwe, ill y end thence'upwy. e upwardly extended rtion is do through the dosh-rd "it and there provided with e hundle 22 which is oleo within convenient reech oi the driver of the therein will flow through the distributor pipes 16 to the respective rin by vity. A drein cock 2t is oonnecte to the dietributing tenh w thet it mey he emptied when w d.

In practice, velve 12 will he closed end the reservoir 5 will he tilled with oil end he t closed etvelve 7. A connection will then he made with the stem 9 to force air into the reservoir end put the oil therein under e desired pressure necessary to force it to d through the hearings oi the vehicle. The check-valve in the stem 9' will cause the hit to be retained in the reservoir to keep the oil therein under the desired ressure. When the heerings ore to he lubricated or flushed with oil underpressure, it is only neceesery to open the valve 112 which will chose the oil in reservoir 5 to puss down into the trihuter tenlr ii and thence through the con nections it to the heerings. in this manner, ell oi the beerings connected to the distrihuter tenh mey be simulteneously lubriceted or flushed under pressure. Noimelly, velve 12 will he kept closed. When the heerings being lubriceted under ressure, velve will else he closed. t it should he desired to continuonely luhr cete the beer hy grevity, mey he done provided with o. velve i 20 which is provided with e stem 2i exopening the valve 20 so that the top of the tank 11 will be open to atmosphere through pipe 18 so that oil in the distributing tank will be fed by gravity through pipe 16 to the bearings.

The invention exemplifies a lubricating system for automobiles in which the distributer pipes are connected to a distributing tank which is supplied with oil from a reser voir under control of a single valve; in which provision is made for lubricating the bearings by gravity when desired, while the oil in the reservoir is retained under pressure; inwhich a large number of bearin may be simultaneously and convenient y oiled.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention,

Having thus described the invention, what it claim as new and desire to secure by Letters Patent, is:

1. In a lubricating system "for automobiles, the combination of a closed oil reservoir, aconneetion for putting the oil in the reservoir under pressure, a. distributing tank, a valve between the reservoir and the tank for controlling the delivery of oil under pressure into the distributing tank, a series of pipes leading from the tank to (lilierent bearings of the automobile, and means to deliver air under atmospheric pressure directly to said distributing tank to permit the gravity flow through said series of pipes.

2. In a lubricating system for automobiles, the combination of a closed oil reservoir, a connection for putting the oil in the reservoir under pressure, a distributing tank, a valve for controlling the delivery of oil under pressure from the reservoir to the tank, and a vent pipe directly connected to the tank to allow the oil therein to be fed to the bearings by gravity when the valve is closed.

3. In a lubricating system for automobiles, the combination of a closed oil reservoir, a connection for putting the oil in the reservoir under pressure, a distributing tank, a valve for controlling the delivery of oil under pressure from the reservoir to the tank, a vent pipe directly connected to the tank, and a valve in the vent pipe for controlling the delivery of air under atmospheric pressure directly to said distributing tank to permit the gravity flow of oil to the bearings when the valve for controlling the delivery of oil from the reservoir to the tank is closed.
